摘要：the influence of social networks on weather insurance adoption and the mechanisms through which they operate. To quantify network effects, the experiment provides intensive information sessions about the product to a random subset of farmers. For untreated farmers, the effect of having an additional treated friend on take-up is equivalent to granting a 13 percent reduction in the insurance premium. By varying the information available about peers' decisions and randomizing default options, we ...

摘要：We study a Conditional Cash Transfer program in which the cash transfers to the mother only depend on the fulfilment of the national preventive visit schedule by her children born before she registered in the program. We estimate that preventive visits of children born after the mother registered in the program are 50 percent lower because they are excluded from the conditionality requirement. Using the same variation, we also show that attendance to preventive care improves children health.

摘要：This paper presents results from a randomized controlled trial whereby approximately 1,000 OLPC XO laptops were provided for home use to children attending primary schools in Lima, Peru. The intervention increased access and use of home computers, with some substitution away from computer use outside the home. Children randomized to receive laptops scored about 0.8 standard deviations higher in a test of XO proficiency but showed lower academic effort as reported by teachers. There were no imp...

摘要：We implement a randomized experiment offering Salvadoran migrants matching funds for educational remittances, which are channeled directly to a beneficiary student in El Salvador chosen by the migrant. The matches lead to increased educational expenditures, higher private school attendance, and lower labor supply of youths in El Salvador households connected to migrant study participants. We find substantial crowd-in of educational investments: for each $1 received by beneficiaries, educationa...

摘要：We estimate the effect of a large rural workfare program in India on private employment and wages by comparing trends in districts that received the program earlier relative to those that received it later. Our results suggest that public sector hiring crowded out private sector work and increased private sector wages. We compute the implied welfare gains of the program by consumption quintile. Our calculations show that the welfare gains to the poor from the equilibrium increase in private se...

摘要：This paper uses a field experiment to test whether intrahousehold heterogeneity in discount factors leads to inefficient strategic savings behavior. I gave married couples in rural Kenya the opportunity to open both joint and individual bank accounts at randomly assigned interest rates. I also directly elicited discount factors for all individuals in the experiment. Couples who are well matched on discount factors are less likely to use costly individual accounts and respond robustly to relati...

摘要：This paper analyzes how evaluators' private information and subjective biases affect evaluations in academia. We use evidence from centralized selection exams in Spain, where evaluators are randomly assigned to promotion committees. Candidates are significantly more likely to be promoted when they are evaluated by an acquainted evaluator, but the source of the premium depends on the nature of this relationship. Our findings suggest that, when candidates are evaluated by their PhD advisor, a co...

摘要：We exploit exogenous variation in legal status following the January 2007 European Union enlargement to estimate its effect on immigrant crime. We difference out unobserved time-varying factors by (i) comparing recidivism rates of immigrants from the new and candidate member countries; and (ii) using arrest data on foreign detainees released upon a mass clemency that occurred in Italy in August 2006. The timing of the two events allows us to setup a difference-in-differences strategy. Legal st...

摘要：Using comprehensive administrative data on France's single largest financial aid program, this paper provides new evidence on the impact of large-scale need-based grant programs on the college enrollment decisions, persistence, and graduation rates of - low-income students. We exploit sharp discontinuities in the grant eligibility formula to identify the impact of aid on student outcomes at different levels of study. We find that the provision of 1,500 euros cash allowances to prospective unde...

摘要：Community-rating regulations equalize the insurance premiums faced by the healthy and the unhealthy. Intended reductions in the unhealthy's premiums can be undone, however, if the healthy forgo coverage. The severity of this adverse selection problem hinges largely on how health care costs are distributed across market participants. Theoretically, I show that Medicaid expansions can combat adverse selection by removing high cost individuals from the relevant risk pool. Empirically, I find that...
